You start every premise with the word " clearly" but some people disagree with most all of them including me. Sorry Theodoros, it just is not that simple .

Hmmm, IMO most of his statements are pretty accurate in and of themselves. What isn't clear is what to do when you want attributes of both lenses, but can/will only have one.

I think it's a little less clear for DX users, for the DOF isolation options. When I'm using the 70-200 it's often for that very effect. Using FX helps here. But starting at f4 on a DX body is a little defeating. And yet often the gist of DX is smaller and lighter, which is exactly what the f4 is.
